On the eve of Idolmaster 2's release, some producer sleuths have managed to get the PS3 title in advance and out some possible download content by examining the game's source.

Look to the right, and you'll see "macf_ranka" and "macf_sheryl." Could these be crossovers with Macross F songstresses Ranka and Sheryl?

This wouldn't be the first time we'd heard Idolmaster and Macross mentioned in collaboration talks. Back when the game's Hatsune Miku crossover was announced, Sega's Hiroshi Utusmi said that he'd like to do a collaboration with Ranka and Sheryl. Of course, as Utsumi was on the Sega side of the collaboration, he was probably referring to a collaboration with Hatsune Miku.

The source also shows Rin and Ren, suggesting that Hatsune Miku could be joined by additional virtualoids.
